Spot welding yog ib qho kev sib koom ua ke siv dav hauv kev tsim khoom lag luam, suav nrog cov tsheb thiab aerospace sectors.Hauv nruab nrab zaus inverter vuam tshuab, qhov tsis kam ntawm qhov chaw vuam ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab qhov zoo thiab kev ntseeg siab ntawm cov vuam.Qhov tsab xov xwm no tshawb txog qhov tsis kam koom nrog hauv qhov chaw vuam thiab nws qhov tseem ceeb hauv kev ua tiav kev ua tiav welds.
Lub ntsiab lus ntawm kev tiv thaiv hauv qhov chaw vuam:
Kev tawm tsam hauv qhov chaw vuam yog hais txog qhov kev tawm tsam uas tau ntsib los ntawm cov hluav taws xob tam sim no thaum nws dhau los ntawm cov khoom ua haujlwm tau koom nrog.Qhov kev tiv thaiv yog cuam tshuam los ntawm ntau yam, nrog rau cov khoom siv, qhov chaw saum npoo, tsim hluav taws xob, thiab kev sib cuag ntawm cov electrodes thiab workpieces.
Cov yam ntxwv cuam tshuam rau qhov tsis kam ntawm qhov chaw vuam:
Cov khoom siv: Cov ntaub ntawv sib txawv muaj qhov sib txawv ntawm cov hluav taws xob conductivity, uas cuam tshuam rau lawv cov kev tiv thaiv hluav taws xob tam sim no thaum lub sij hawm vuam.Cov khoom siv hluav taws xob ntau dua, xws li cov hlau tsis muaj steel, feem ntau muaj kev tiv thaiv siab dua piv rau cov ntaub ntawv xws li tooj liab lossis txhuas.
Deg tej yam kev mob: Qhov huv thiab qhov chaw ntawm lub workpieces ho cuam tshuam rau hluav taws xob kev sib cuag thiab, yog li ntawd, qhov tsis kam ntawm qhov chaw vuam.Oxidation, coatings, los yog cov kab mob ntawm qhov chaw ua haujlwm tuaj yeem ua rau muaj kev tiv thaiv thiab cuam tshuam rau kev tsim cov vuam zoo.
Electrode tsim: Cov qauv tsim thiab cov duab ntawm cov electrodes cuam tshuam rau thaj tsam ntawm kev sib cuag thiab siab siv rau cov khoom ua haujlwm.Kev tsim hluav taws xob tsim nyog ua kom muaj kev hloov pauv tam sim no thiab txo qis tsis kam ntawm electrode-workpiece interface.
Kev tiv thaiv kev tiv thaiv: Kev tiv thaiv kev sib cuag ntawm cov electrodes thiab workpieces cuam tshuam rau tag nrho cov tsis kam ntawm qhov chaw vuam txheej txheem.Nws yog ib qho tseem ceeb los tsim kom muaj kev sib cuag hluav taws xob zoo ntawm cov electrodes thiab cov khoom ua haujlwm kom txo tau qhov tsis kam thiab ua kom muaj txiaj ntsig zoo tam sim no.
Qhov tseem ceeb ntawm kev tswj tsis kam hauv qhov chaw vuam:
Kev tswj qhov tsis kam ntawm qhov chaw vuam yog qhov tseem ceeb rau kev ua tiav zoo ib yam thiab zoo welds.Qhov kev tiv thaiv ncaj qha cuam tshuam rau kev tsim hluav taws xob, tsim nugget, thiab tag nrho cov vuam lub zog.Kev ua haujlwm zoo tshaj plaws ua kom muaj cua sov txaus los yaj cov khoom ua haujlwm thiab tsim kom muaj kev sib raug zoo ntawm cov khoom siv hlau.Qhov sib txawv ntawm qhov tsis kam tuaj yeem ua rau qhov tsis txaus weld fusion, cov pob qij txha tsis muaj zog, lossis txawm tias electrode puas.
Nyob rau hauv nruab nrab zaus inverter welding tshuab, qhov tsis kam koom nrog hauv qhov chaw vuam plays lub luag haujlwm tseem ceeb hauv cov txheej txheem vuam.Kev nkag siab txog yam cuam tshuam rau kev tiv thaiv thiab tswj nws nyob rau hauv qhov xav tau ntau yam yog qhov tseem ceeb rau kev tsim cov chaw welds txhim khu kev qha thiab ruaj khov.Los ntawm kev ua kom zoo xaiv cov khoom siv, tswj xyuas qhov chaw ua haujlwm huv si, tsim cov khoom siv hluav taws xob tsim nyog, thiab ua kom muaj kev sib cuag ntawm electrode-rau-workpiece, cov neeg ua haujlwm tuaj yeem tswj xyuas kev ua haujlwm zoo thiab ua tiav qhov chaw welds uas xav tau thiab kev ua haujlwm zoo.
